Specification of Letters Patent.

Patented Feb. 12, 1907.

Anplication filed April 23. 1906- Serial No. 814,214.

To all whom it may concern:

Be it known that we, BIRGER LJUNesTRoM and FREDRIK LTUNGsTRoM, subjects of the King of Sweden, and residing at Stockholm, Swe en, have invented certain new and useful Im rovements in Apparatus for O erating kin -Machines; and we do here y declare the Following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

' This invention relates to apparatus for operatin milking machines actuated by Ineansoi a reciprocatin motion, and it more especially relates to mi 'ng-machines of the kind shown and described in United States Letters Patent No. 784,693, granted March 14, 1905, wherein a plurality of pistons moving in cylinders are pressed successively upon the teats, said istons bein actuated to and .fro by means 0 a pulsatingFiquid put in motion by means of a pump.

The invention has for its object to operate either in a cow-house or open field several milkin -machines simultaneously by means of mec anism that is inexpensive and which may be easily and quickly installed.

The invention is schematically shown in the annexed drawings in several constructional forms, in which Figure 1 is a plan of a cow house' havin an ap aratus installed therein constructed accor ing to this invention, the milkingmachines being omitted; Fig. 2, a similar view showing a modified form of apparatus. Fig. 3 is an elevation of another form of apparatus, and Figs. 4 and 5 show the application of the apparatus in connection with a milking-machine and pump for operating the same. Fig. 6 shows the application of the apparatus in connection with a milkingmachine and bell-crank lever connections for operating the same.

In Fig. l a well-known form of a hay-rack is designated by the letter a, on two sldes of which are constructed a plurality of stalls b for the cows, the end walls of the house being designated by the letter d. Wires or rods 0 are stretched between the walls d at the proper distance from the racks, and on these wires are mounted a plurality of pumps or the like 8, to each of which is connected a milking-machine 1). (Shown in Fi s. 4, 5, and 6 At each of the four corners o the rack a 18 mounted a post e, and on each post 1s mounted a bracket f, in which is mounted a bellcrank lever h, secured therein by and adapted to swing on a pin'g. The ends of these levers are connected with each other by means of wires or rods i, running parallel to the rack 01., and by wires or rods is, running at right angles to the Wires 6, forming a rectangular framework.

As above stated, a plurality of motors are rigidly mounted on the wires 0. pumps are used for operating the machines, the piston of each pump is connected to one of the wires i by means of a connecting-piece t, Fig. 5. A reciprocating motion is imparted to the wires 7 and consequently to the pistons, by means of a handle 1, formed on one of the bell-crank levers h, thereby operating all of the pumps simultaneously.

In Fig. 2' another means is shown for mounting the reciprocating rods or wires 'i. At each end of the rack a'is mounted a stud m, on which is mounteda beam n, adapted torock on a pin 0, the two ends of each beam being connected by the wires or rods i, running parallel to the rack a. Motion may be imparted to the rocking beams by means of a lever or handle I, which may be operated by any suitable means.

Fig. 3 illustrates still another way of mounting the reciprocating wires. In this instance an independently-operated wire is used for each set of stalls. On one of the posts a at one end of the rackis mounted a double bell-crank lever 77., adapted to rock on a pivot o, and on a post e at the opposite end of the rack is mounted a pulley p. The wire i, being connected to one arm of the bellcrank lever 12/, passes over the pullev p and is connected to the other arm of said bellcrank lever. Any suitable means may be used for operating the free arm of the bellcrank whereby the two parts of the wire move in opposite directions. As indicated in dotted lines, the wire instead of being secured to two arms of the lever maybe secured to one arm only, the other end of the wire being secured to a spring or a weight r.

When

I In F' 6 there is shown .another modifiedform. n the milking-machine a rod '1' is arranged to have 'a reciprocating motion. By means of a bell-cranklever a, swin ing on the in '0, the said rod 1' is connected with rod 1, w ich is secured to the one end of the bellcrank lever 2, swinging onthe in 3, secured to the wire '5. The other end the lever 2 is secured to the wire 0. When the wire i ets a reciprocating motion, said motion -wil be imparted to the rod r b means of the bellcrank lovers 1/. and 2 an the rod 1, connecting them. V

While the apparatus is shown and described as being installed in a cow-house, it

' is a parent that it may be erected in an open fiel b erectin osts for supportin the wires i a nd the b llbrank levers h. g

We claim I 1. In an apparatus of the character described, the combination with the milking mechanism of a supportin member, a motion-transmitter supporte' thereby, a rod connected with the motion-transmitter, means to reciprocate the rod to actuate the motion-transmitter and means connecting mechanism, of a supporting member, a =cyl-.

the transmitter and the milking mechanism. 2. In an apparatus of the character described, the combination with the milking mechanism of a sup orting member, a cylinder supported there y, a plunger in the cylinder, a rod connected with the plunger,

means to reciprocate the rod to actuate the plunger, and a conduit connecting the 'cylinder and milking mechanism. 3. In an apparatus of the character described, the combination with the milking inder secured thereto, a plunger in the cylinder adapted to reciprocate parallel to the supporting member, a rodto which the plun- 'ger is connected, means to reciprocate the v rod to actuate the plunger, and a conduit connecting the cylinder and. mechamsm. v

4. In .an apparatus of the character described, the combination with the milking mechanism of two parallel stations. supconnected with the m1 mechanism,--a plunger in each cylinder a apted to reciprocate parallel to the supportmg members, an operati member lurality of cy inders' mounted parallel to and in proxirmty to each supporting member, means; to connect the operating members, means to connect the latter with each plunger, and means to rock the connections of the operating members.

5. In an apparatus of the character de-,

scribed, the combination with the mechanism of two horizontally-mounts parallel supporting-rods, a plurality of supports, a rocking member pivoted .on each support, wires parallel to the su ocrtingirods connecting the rocking mem ers, and

means connecting the said members with the milking mechanism.

6. In an apparatus of the character described, the combination with themilk-ing mechanism, of two stationary horizontallymounted supporting-rods, a plurality of perpendicular supports, a bell-crank lever pivoted on each perpendicular support,- wires parallel to the supporting-rods connecting the bell-crank levers in pairs, laterally-disposed wires connecting the pairs of levers, means to rock the; levers and wires connecting the levers with the milking mechanism.

In testimony that we claim the foregoing as our invention we have. signed our names in presence of two subscribing witnesses.
